  Abstract: Composite sandwich structures, renowned for their high flexural stiffness and low weight, are widely used across industries such as aerospace, automotive, and marine. However, their durability can be compromised by impact-related damages, which affect both the core and face sheets. This study explores the performance of corrugated sandwich panels compared to conventional designs under low-velocity impacts. Using a drop weight impact testing machine, panels made from polyurethane foam cores and …
